Burned Out on EVE – Thinking of Returning in a Few Years, What Happens to My Assets?

I’ve been playing EVE for a long time, but I’ve hit a massive burnout. The game just doesn’t feel fun anymore, and I think I need to step away for a few years. Maybe I’ll come back, maybe not—who knows?

My assets are mostly in null sec, and I’m wondering what happens if I take a long break. Will they get moved to asset safety automatically, or will I have to deal with a mess if/when I return? Also, if they do go into asset safety, do I need to pay to retrieve them, or is it free after a certain period?
